The invention relates to a frame made of shaped sections which preferably has a rectangular or square shape and is designed to receive plate-like elements having a front, a back and sides. At least one of the shaped sections has an L-shaped part so as to support the plate-like element at the back and hold it at the sides. Said shaped section can also present only one supporting surface so as to support the plate-like element only at the back. The other shaped sections comprise a first U-shaped part which is open towards the plate-like element and receives the edge area of said plate-like element. At least one of the shaped sections having a U-shaped part comprises a second U-shaped part which is open to the front or back. The array of plates and frames made of shaped sections provided for by the invention makes it possible, among other things, to use such arrays as roof elements. |
